MACHINE'. FOR FORIVIING INTERLOCKING EYES.

SPECIFICATION forming part of Letters Patent No. 897,17 5, datedFebruary 5, 1889.

Application filed September 29, 1888. Serial No. 286,735. (No model.) l

4iT@ @ZZ whom it may concern:

3 Be :it known that I, ROBERT Firmas, of the jcity of Decatur, county ofMacon, and State forming interlocking eyes have employed av rotatinghead to coil the ends ofthe wires around a stud and l'orm the interlock.This construction has necessitated the introduction of a device to raisethe ends over the bodies of the wires; or, in the absence of suchdevice, the ends have been raised by the hands of the operator attendingthe machine. The inconvenience and loss of time attendin the raising theends by hand are manifest, and the introduction of an auxiliary devicethat would automatically perform that operation has been diflicult andsomewhat unsatisfactory. In my invention the rotating1 head is dispensedwith, and the interlock is formed by two pairs of levers that act invertical planes while describing arcs having approximately-horizontalchords. The wires to be inter-locked lie in about the same horizontalplane on opposite sides of the stud, with their ends projecting beyondthe stud in opposite directions, and they are held more or less firmlyagainst longitudinal and lateral misplacement. The pair of leversirstito act are pivoted below the wires and swing in planes at rightangles thereto. In their initial motion they strike the 'ends of thewires while moving slightly upward, carrying them over the bodies andbending them about onefourth around the stud. The pair of levers secondto act arepivoted above the wires and swing at right angles to the pathsof the first pair of levers. In their action they carry the ends of thewires about one-fourth farther around the stud and slightly depressthem. The interlock is completed by a second action of the first pair oflevers on interchanged ends.

The operat-ion of the levers is performed by a succession of quickstrokes that bend the ends around the stud without tending materially todraw the wires lengthwise, and this is an advantage over the rotating`heads which by continuous friction tend to draw the wires legthwise andprevent nice accuracyin spacing the distance between eyes.

From the above it will appear that the principal objects ol my inventionare to produce a machine that will carry the ends of the wires over thebodies thereof while forming the interlockii'lg coils, and that will nottend to draw the wires lengthwise during such operation. Other featuresof less importance will appear in the detailed description and in theclaims.

In the drawings accompanying and forming a part of this specili'cation,Figure l is a front elevation of a machine embodying my invention. Fig.2 is a front elevation of the novel. features of the machine enlargedand detached. Fig. 3 is a section on broken line .e .e in Fig. 2. Fig. 4is a side elevation of my device with the first move made in theformation of the interlock. Fig. 5 is the same view showing the secondmove made. Fig. 6 is the same view showing the third move made. Fig. 7is a face view of certain parts, showing their position at the stage ofthe operation shown in Fig. 6. Fig. 8 is a plan of the wires, the stud,the standard, and the handle used to operate the stud and stan dard, thewires being arranged preparatory torforming the interlock. Fig. 9 is thesame plan showing the wires cramped by projections on the standard. Fig.l() shows the position of the wires when the machine is first put in thecondition shown in Fig. 5, the broken lines and arrows indicating, as insubsequent figures, the directions the operative ends of the levers havepursued. Fig. 1l shows the position of the wires when the machine is inthe condition shown in Fig. 6. Fig. l2 shows the interlock completed bya return to the condition indicated in Fig. 5.

In Fig. 13 the eyes are shown as completed by ceiling the ends of thewires around the bodies thereof, and in Fig. li the wires, with theirinterlocking eyes, are shown detached from the machine.

The stud around which the wires are bent is indicated in the detaildrawings by reference-letter c. It has longitudinal motion in tubularstandard a, and when at rest is held sheathed in the same by spring c.(Shown in Fig. 3.) The standard a has partial rotation IOO in a socketformed in base-plate A, and it is movingI the standard.

The lever 1/ is next swung' to the depressing them.

the position shown in Fig. o will cause the leversf g/ to carry the endsot' the wires to the position shown in Fig. 12, and so complete theinterlock. The motions necessary to etlect the opera-tion can be madewith great rapidity. tain an erect position, and they are. notparticularly tiresome.
